Cannot uninstall

@aitala I'm sorry, but this isn't much information to go on. I don't experience the same problem when I try to uninstall the module with Drush. Is this error appearing on every page of the site? You don't explain what else you tried to do to fix the problem. Did you try refreshing the cache with drush cr. Sometimes that isn't even enough for me lately and I actually have to clear it at /admin/config/development/performance. If you can roll back the DB (or reinstall Aggregator to get the site working again), then you might try uninstalling the module through the admin UI too. Sometimes that prevents problems that uninstalling via Drush won't.

Hi,

I tried both a UI and drush un-install... cleared cache many times, tried to re-install Aggregator, etc.

What I had to do was manually remove all the Aggregator feeds, a View Mode (or two) for Aggregator display, then remove references to 'Aggregator RSS feed' manually from the database. At that point I was able to un-install the module... as far as I remember...

So I guess you can close this as I'm not sure what happened to mess up the original install - I wasn't even using the feeds within the site.

Ok, thank you for reporting back. I'm sorry you had this trouble.
